It is made possible to perform a code search both at a high speed and with efficiency based on a position specified by a user. An apparatus includes an operation unit configured to receive a position instructed by a user, the instructed position indicating a position of a code that exists on a document, a scan unit configured to obtain image data by scanning a document after the operation unit receives the instructed position, a search unit configured to search for a code at a position corresponding to the instructed position in the image data obtained by the scan unit, a decoding unit configured to obtain information by decoding the code that has been found by the search unit, and a processing unit configured to perform processing for the image data based on information that is obtained by the decoding.
